So a lot of people seem to be struggling with this concept and so I'm making another card to help!

Ex: 공부 열심히해!
it literally translates to- to study to do well, and when you put that together it means study well!
Subject- to study
Verb- to do well
subject+verb= to study + to do well
put it together we literally get 'To study well'
Another example of Subject+Verb;
유나는 달린다. yunaneun dallinda. – Yuna runs. (Yuna- Subject, runs- Verb)
유나 – Yuna (a name)는 – Neun – (topic marker and points to Yuna, because we’re taking about her)달린다 – Dallinda – Run

I hope this helped! I'll be making more Korean Sentence Structure along with other cards if you want.
ps- anyone watch BTS Run mv yet!? it gave me the feels
